Upgrading Debian Etch to Lenny
Debian Etch has been serving me well for a few years with wonderfully easy and infrequent maintenance.
However it’s at the end of its life
http://www.debian.org/News/2010/20100121
So I’ve upgraded to Lenny following these instructions
http://www.debian.org/releases/lenny/i386/release-notes/ch-upgrading.en.html
It was remarkably painless
One small problem with the mail system.
Errors were encountered while processing:
exim4-config
imapproxy
exim4-base
exim4-daemon-light
courier-imap
at
bsd-mailx
courier-imap-ssl
mailx
But scrolling upwards I got a more helpful error message
A package failed to install. Trying to recover:
Setting up exim4-config (4.69-9) ...
DEBCONFsomethingDEBCONF found in exim configuration. This is most probably
caused by you upgrading to exim4 4.67-3 or later without accepting the
suggested conffile changes. Please read
/usr/share/doc/exim4-config/NEWS.Debian.gz for 4.67-2 and 4.67-4
So I purged exim, deleted the config files, reinstalled it and now everything seems good.
